Corsair 4000d temps

I’m not sure if what I’m experiencing is normal but I have just moved my pc components from my old case to the Corsair 4000d but I’m noticing the top of the case where the AIO is mounted is quite hot to the touch . Is that normal ?

My pc specs are (yes they are old ) :

• asus z370-I
• 8700k
• Corsair 16g RAM
• Corsair icue link 100i (new)
• x3 front mounted Corsair icue link fans (new)
• x1 read Corsair icue link fan (new)

My cpu core temps are sitting around 56c with max 87deg
